摘要： An apparatus for molding balloon catheters is disclosed. The balloon may be molded by providing a polymeric tube within a mold having an interior cavity in the shape of the desired balloon. Microwave energy, which may be generated by a gyrotron, may then be directed toward the mold, to heat the polymeric material without heating the mold. Once heated, pressurized fluid may be injected into the tube to blow the polymeric material against the interior cavity whereupon the material can cool to form the balloon or can be further heatset by additional microwave energy and be cooled to form the balloon.

摘要： An extruder forms shaped bodies from plastics-filler mixtures having a filler content of more than 50% by volume. The extruder comprises a product feed device, an outer mouthpiece and two barrels arranged coaxially between the product feed device and the outer mouthpiece. The first barrel (input cone) having an inside wall provided with grooves essentially parallel to the longitudinal extent of the barrel is connected with the product feed device. The second barrel (output zone) is connected with the outer mouthpiece. A screw arranged in the first barrel conveys material into the second barrel. Separate tempering arrangements for the first barrel, for the second barrel and for the mouthpiece control the desired operation temperatures in the extruder. Preferably, the extruder additionally includes a mandrel connected with the screw and arranged in the second barrel.

摘要： A thermoplastic resin film wherein the variation in thickness of the film in the longitudinal direction is not more than 5% and the ratio "Pw1/PwT" of the sum of spectral intensities of wave-number components present in the wave-number range of 0.15 to 0.45 (1/m) (Pw1) to the sum of spectral intensities of the full wave-number range (PwT) determined when a wave form of the variation in thickness is subjected to analysis of Fourier transformation is not more than 0.20, and wherein the variation in thickness of the film in the longitudinal direction is not more than 5% and the ratio "Pw2/PwT" of the sum of spectral intensities of wave-number components present in the wave-number range of 1.00 to 2.00 (1/m) (Pw2) to the sum of spectral intensities of the full wave-number range (PwT) is not more than 0.15. In such a film, the uniformity in thickness can remarkably improved, and snaking and wrinkles in post processing can be prevented.

摘要： An improved extrusion method is employed in a process which is used to form tubing for medical applications. The method includes providing an extrusion apparatus having a die which includes a die cavity and a mandrel within the die cavity. The die is rotated in a first rotational direction while the mandrel is rotated in a second rotational direction opposite the first direction. While the die and the mandrel are rotating, a PTFE paste is passed through the annular passage defined between the die and the mandrel. The die cavity is cooled to maintain the PTFE paste passing therethrough at a substantially non-elevated temperature.

摘要： A film blowing head for extruding a tubular web of a thermoplastic synthetic melt consists of at least one inner cooling ring and a pipe passing through the blowing head, wherein a central pipe is arranged with the formation of an annular space. The annular space is placed in an air conducting communication with the inner cooling ring. The cooling and supporting air is fed via lines into the annular space and is drawn off again through the central pipe. To permit cooling with very cold air, the pipe feeding the cooling air is surrounded, in the zone of the blowing head, by two concentric pipes with the formation of two annular spaces. The two annular spaces are connected with each other in the zone of the plane of the outlet nozzle gap of the blowing head by an overflow compartment that is closed towards the outside. Warm air is fed to one of the annular spaces, and is drawn off again through the other annular space.

摘要： Apparatus and method for fabricating films, especially films containing vinylidene chloride copolymer, wherein the process is susceptible of continued operation over an extended period of time greater than a few days. The process typically can operate for at least 2 weeks between shut downs for cleaning the die. The apparatus comprises a coextrusion feedblock 20 in combination with an annular extrusion die 10 having a crosshead mandrel 11, and means for conveying the exit stream 24 from the feedblock to the die. The particular apparatus combination especially reduces the rate of carbon buildup in the extrusion apparatus during extrusion of VDC-copolymer, such that the extrusion process can be operated for a longer time between shutdowns for cleaning and maintenance of the die. The invention further includes novel tubular films 32 made with the apparatus and methods of the invention, and packages made from the films. In general, the method of the invention produces tubular films having more layers than the annular extrusion die has annular orifices.
